    摘要: The present invention relates to an optical characteristics switching mechanism for switching optical characteristics of an optical system by selectively locating an optical element in an optical path of the optical system. The optical characteristics switching mechanism of the present invention comprises optical characteristics switching element for selectively arranging a holder holding the optical element at either of a first position at which the optical element exists in the optical path and a second position at which the optical element is out of the optical path, by rotating the holder with use of a magnetic force.
